Introduction
Technology has made everyone’s life more convenient – it’s also restructuring the human brain, altering our actions, thoughts, and actions. Modern technology has become a vital part of our lives, and most things are designed and created around it. As a result, people globally have developed behaviours that were never a tradition in human history.
Biosignal analysis is among the key topics that scientists have tried to develop across the past 100 years to restructure the human brain and understand different associated diseases. An electroencephalogram (EGG) is one of the most popular technologies that provide biosignal electrical representation that reflect alterations in human brain activity.
In this article, you’ll learn more about an egg cap and how technology is assisting with brain research. You’ll also learn some of the use cases where electroencephalograms can be utilised. Keep reading to discover more!
What is an EEG?
Electroencephalogram (EEG) is the brain’s electric fields’ non-invasive measurement. It involves electrodes placed on the human scalp to record potentials originating from the current flow around and in neurons. Electroencephalogram is approximately 100 years old – this long history has provided it with a diverse and rich spectrum of use cases.
While many other techniques are used for brain data acquisition, including positron emission tomography and magnetic resonance imaging, an EEG has stood the test of time to remain the most popular way of assessing the activity of the human brain. It has remained a popular technique thanks to its high temporal resolution, low cost, and simplicity.
Evolution of an EEG and How it’s a Big Part in Understanding the Human Brain
Scientists have been focusing on human brain signals since the start of the last century. Since then, they have developed multiple attempts and ways to interpret and understand those signals. The general EEG signals’ emergency and development occurred in 1875 by Richard Caton, who discovered the availability of electrical current in the brains of monkeys and rabbits.
In 1912, Vladimir Vladimirovich Pravdich-Naminsky, a Russian physiologist, published the first brain signals detection and evoked potentials in mammals. Hans Berger, a German neurologist, recorded the first brain signal of a human in 1924. The scientist used a simple radio device to amplify the human brain signal and recorded it on graph paper.
Hans Berger named the device “EEG”. Since then, many scientists have improved the device and made additional discoveries, allowing it to be a huge part of understanding the human brain. Currently, an EEG is used to find alterations in the human brain activity that are key in diagnosing brain disorders.
Use Cases Where Electroencephalogram Can Be Utilised
EEG is popularly used in the healthcare industry. It helps health experts to diagnose different brain disorders, including epilepsy, sleep disorders, and Attention Deficit Hyperactivity Disorder.
It also helps in the detection of brain tumours, brain damage from head injuries, stroke inflammation of the brain, and Creutzfeldt-Jakob disease. Other industries also use EEG research, including neuromarketing, research applications, brain-computer interfaces, and social interaction.
